18, Northampton Street

This is a house built after 1819, with a later addition of a second floor. The design is attributed to GP Manners. The front is constructed of limestone ashlar, and has a double-pile, parapeted roof. The left party wall is coped and incorporates two ashlar stacks with early clay pots. A staircase is located to the rear.

The house is three storeys and has a basement, with a two-window front. The first floor has an eight/eight-sash window to the left, in a plain reveal with a stone sill and wrought iron balconette, and a similar six/six-sash window to the right. The second floor has two six/six-sashes in plain reveals with stone sills. The ground floor has an eight/eight-sash window to the left in a plain reveal, with a timber lintel and stone sill; to the right, a six-panel door with reeded and fielded panels (having voided corners) and a single step in a round moulded reveal. The fanlight above the door is now blocked. The basement has two/two-sashes in splayed reveals, partially set above ground level and with grating in the pavement. The building features a moulded cornice above the first floor, a small moulded eaves cornice, and a coped parapet. A lead hopperhead and a part-lead downpipe are on the front left. The rear elevation has glazing bar sashes. The interior has not been inspected.

Northampton Street and the surrounding development began around 1791, designed by Thomas Baldwin, acting as trustee for William Pulteney. Construction continued from 1794, following the bankruptcy of the principal contractors, with plans and elevations on leases signed by Thomas Chantry and John Pinch (his first major work). The street was completed after 1819, with plans and elevations on leases signed by GP Manners. Bomb damage in 1942 and subsequent redevelopment significantly altered the lower part of the street.
